Personal Information

Learning Objectives Define Personally Identifiable Information (PII) and provide examples. Group related personal information into a single data structure, like a dictionary or object. Access specific pieces of personal information from a data structure using a key. Validate the data type of a variable containing personal information (e.g., checking if age is a number). Combine multiple variables of personal information into a single, formatted string for output. Explain why it's important to handle personal information carefully in a program. Have you ever filled out a form online to create a new account? 🤔 Where does all that personal information go and how does the computer understand it? In this lesson, we'll explore advanced ways to handle personal informati...

The 'key' is the label (like 'name'), and the 'value' is the data itself (like 'Alex').In {'age': 12}, 'age' is the key and 12 is the value. Data Validati...

Creating a Data Structure (Dictionary) variable_name = { 'key1': value1, 'key2': value2 } Use curly braces {} to create a dictionary. Inside, list key-value pairs. Keys are usually strings in quotes, followed by a colon, then the value. Separate each pair with a comma. Accessing Data from a Structure variable_name['key'] To get a value out of a dictionary, use the dictionary's variable name followed by square brackets [] containing the key (in quotes). Basic Data Type Check if is_number(variable): ... Use a conditional statement (like 'if') with a function that checks the data type to make sure a variable contains the kind of data you expect before you use it.
